Reaching for the top

What am I training for? As a master runner, I have a goal of reaching the #1 world ranking in the 800m and 1500m. As a sub master I reached #13 in the world in the 800m. I am looking to improve my world ranking to #1 this year as a true master. I think it will take about a 1:53 for the 800m and 3:49 for the 1500m. These times are a few seconds slower than my life time bests.
